22621688 ÷ 579 
The aim is to understand the frequency of 579 in 22621688.

Step 1:
579 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 579

Let's proceed to step 2:
579 can be fit into 22 0 times, resulting in a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 579

Step 3:
When dividing 226 by 579, we get 0 with a remainder of 226.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 226 leaves us with 226.
Take the next digit (2) from the dividend and append it to 226, then repeat: 2262 / 579

Let's proceed to step 4:
579 goes into 2262 3 times with a remainder of 525.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1737 away from 2262, we end up with 525.
Append the next digit (1) from the dividend to 525 and continue with: 5251 / 579

Let's proceed to step 5:
579 goes into 5251 9 times with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we take 5211 away from 5251, we end up with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 579

Moving on to step 6:
The number 579 fits into 406 0 times, leaving a remainder of 406.
Put 0 as the next digit of the answer. 
Result so far: 390.0
If we subtract 0 from 406, we get 406.
Grab the next digit (8) from the dividend, add it to 406, then carry on: 4068 / 579

On to step 7:
When dividing 4068 by 579, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 3907.0
If we subtract 4053 from 4068, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 579

Going ahead to step 8:
579 can be fit into 158 0 times, resulting in a remainder of 158.
Write down 0 as next digit of the result. 
Result so far: 39070.0
Deduct 0 from 158 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Moving on to step 9:
579 can be fit into 1580 2 times, resulting in a remainder of 422.
The next digit of our result is 2. 
Result so far: 39070.2
Subtracting 1158 from 1580 leaves us with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 10:
The number 579 fits into 4220 7 times, leaving a remainder of 167.
Put 7 as the next digit of the answer. 
Result so far: 39070.27
If we take 4053 away from 4220, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Going ahead to step 11:
The number 579 fits into 1670 2 times, leaving a remainder of 512.
Write down 2 as next digit of the result. 
Result so far: 39070.272
Subtracting 1158 from 1670 leaves us with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Advancing to step 12:
The number 579 fits into 5120 8 times, leaving a remainder of 488.
Use 8 as the next digit of our solution. 
Result so far: 39070.2728
Subtracting 4632 from 5120 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 13:
When dividing 4880 by 579, we get 8 with a remainder of 248.
The number 8 becomes the next digit in our result. 
Result so far: 39070.27288
If we take 4632 away from 4880, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

The final outcome is 39070.27288, with a leftover of 0.000248.
